This invention relates to metal doors and frames therefor adapted to beassembled with walls and other structures of brick work or masonry tocover openings left in such structures or walls. The openings with whichsuch doors are most commonly used are those provided at the base ofchimneys for removal of ashes, soot, etc., accumulating at the bottom ofthe chimney. Doors of this type are also applicable to the ash pitopenings and entrance to the fuel spaces of brick furnaces and to avariety of other uses. The specific embodiment chosen for illustrationherein a door and frame of a standard size for useas the clean out doorat the bottom of a chimney, but this illustration is not to be taken asa limitation of the utility and scope of the invention, for. the sameprinciples may be applied in doors of any size to be placed in anopening of corresponding dimensions in masonry.

walls and other structures of any character whatever. The objects of theinvention are to provide in a frame, associated with a door of thischaracter, means for effecting a more secure anchorage -in the brickwork or masonry than has been possible heretofore and to facilitate thebuilding of the wall or structure with the frame in place therein. Theparticulars of the new features by which these and other related objectsare accomplished, are disclosed in the following specification, inconnection with the drawing, and particularly recited inthe appendedclaims.

Inthe drawing,--

Fig. 1 is a-front elevation of a section of a brick chimneywall with myimproved door frame and door built into it;

Fig. 2 is an elevation of the rear side of the same wall and door frame;

Fig. 3 is a perspective view of the frame and associated door as viewedfrom the rear and from above; I

Fig. 4 is a section on line 4--4 of Fig. 1.

In the drawing, 1 represent the door, 2 the frame, and 3 the wall; theframe and door being coupled together by hinges i and 5 of any ordinaryor other suitable character and having cooperating hook and hasp members6 and 7 for holding the door in closed position, these being also ofusual or any other suitable character. A

-. handle 8 is provided on the door as usual.

This frame comprises the walls 10, i0 and includes flanges extending onfour sides as a facing to overlie the borders of the hole in the masonrywall wherein the frame is set. At the top of the frame is the horizontalflange 11 which is supported and reinforced by the adjacent framemembers-10, and extends rearwardly.

This flange is located at the top of the opening; It has a purpose andfunction not served by any corresponding frame structure heretoforemade, which is to support the masonry structure above the'opening and toanchor the frame in place during the building of the masonry, andthereafter. To serve these purposesthe flange 11 has a width, rearwardlyfrom the plane of the facing flanges at least equal to a major proportion of the width of the individual bricks or blocks of which themasonry structure is built. This in order that bricks, etc.,-laid uponit in the regular order of building the wall above the open ing, will bestably supported and will not tip over or slide off. At oppositeends ofthe iiange 11 are extensions 15 which project beyond the adjacentmembers 10; and preferably also beyond the outer edges of the facingfiangessufiiciently to overlap the adjacent bricks or blocks 16 and 17of the'wall at each side of the opening.

'In the installation of a clean-outdoor of this character, the wall isbuilt up in the ordinary way with an opening of suitable height andwidth to receive the members 10 freely, and in any desired location.When the wallhas been builtup on each side of the opening to therequired height, the frame is placed therein with the extensions restingon the bricks or blocks of thetopmost course on each side of theopening, and the body of the frame is placed close againstthe outer sideof the wall, overlapping, and extending beyond, the boundaries of theopening, as'shown in Fig. 1. The next course is then laid, and thosebricks or blocks which are laid over the opening rest on the flange 11and are supported thereby. This flange and its lateral extensions are ofa thickness approximately equal to, or possibly slightly less than, thethickness of mortar laid between the courses, and if desired, a thin bedof mortar may be laid on the flange to bindthe bricks of the next uppercourse. But these few bricks may be laid withoutmortar under'them ifdesired, since the mortar between the adjacent bricks and between themand the ones of the next higher course securely hold the few brickswhich overlie the top wall of the frame.

The improved frame herein described has the conspicuous advantages thatits extensions or lugs 15 give it a stable support in the wall openinguntil superposed courses have been laid; that such lugs furnish apermanent bond or interlock after the wall has been further built up,whereby all possibility 'of the frame becoming accidentally dislodged isexcluded without necessity of placing mortar between the frame at thebottom and sides of the opening; and that the flange 11 affords initself a support for the bricks of the upper courses. In these respectsmy improvement marks a decided advance over prior practice in respect todoors of this class. Heretofore the door frames used for the clean-outopenings of chimneys, fire and ash pit openings of brick furnaces andthe like, have had a narrow rear flange or web bounding all four sidesof the opening, and have lacked any equivalent of the wide flange l1 andits extensions 15 here shown. It has been necessary then to fill in thespace between the frame flanges and the sides of the opening with mortarand prop up the frame or hold it by some temporary fastening until themortar has set, and to lay a thin board or shingle across the top of theopening to support the bricks over the opening. This practice, in spiteof its inconveniences, has been followed generally by workers skilled inthe art for years. All difficulties incident thereto are avoided by myinvention, and time and labor are saved in setting the frame andbuilding the wall over it, while the frame is more securely anchored atthe same time.

Preferably the frame is made of cast iron, as usual with articles ofthis class, because of the simplicity and low cost of making it of suchmaterial by such mode of manufacture. But other suitable materials maybe fabricated in other ways to produce the same result within the scopeof the invention. Such frames may be made in any proportions anddimensions suited to the uses to which they are put and the dimensionsof the bricks or other blocks of which the wall is made. In any case thefront to rear width of the flange 11 is at least equal to a majorproportion of the corresponding dimension of the bricks, so as to give astable support for those which are laid upon it. As designed for wallsmade of common brick, such width is about three inches. While thethickness of this plate and of its extensions may be varied withinlimits, as previously explained, I prefer that it shall not be greatenough to cause appreciable disalinement of the bricks laid upon it fromthe rest of the course in which such bricks form a part.

What I claim and desire to secure by Letters Patent is:

1. A frame for application to an opening in a brick wall or the likehaving a top plate or flange at the rear side of the frame perpendicularto,

the plane thereof arranged to be in a horizontal plane when the frame isso applied, with extensions at each end of said plate and in the sameplane therewith adapted to be confined between contiguous courses ofsaid wall.

2. A frame for application to an opening in a brick wall or the likehaving a top plate or flange at the rear side of the frame perpendicularto the plane thereof, with extensions at each end of said plate adaptedto be confined between contiguous courses of said wall, said top platehaving a front to rear Width equal to a major proportion of the width ofthe bricks or blocks whereof the wall is composed, whereby to supportsaid bricks or blocksover the opening.

3. A door frame for insertion into an opening in the masonry wallcomprising a frame body having a central opening, lugs at each side forsupporting the frame on the masonry at each side of the unfinishedopening, facing flanges extending from the boundaries of said opening,and a top, horizontal, rearwardly extending flange having a width equalto a major proportion of the width of the bricks of which the wall iscomposed, whereby to support the bricks laid across the opening in thewall.

4. A door frame for insertion into an opening in the masonry wallcomprising a frame body having a central opening, facing flangesextending from the boundaries of said opening, and a top, horizontal,rearwardly extending flange having a width equal to a major proportionof the bricks of which the wall is composed, whereby to support thebricks across the opening in the wall, and said frame havinghorizontally disposed lugs at the rear of said body and at each side ofa thickness substantially equal to the normal separation between coursesof the wall adapted to be received between such courses and locked inthe wall thereby.

5. The combination with a brick wall or the like having an opening, of adoor frame in such opening having extension or facing flangesoverlapping the borders of the opening and a horizontal rearwardlyextending flange provided with extensions at each end entering betweencourses of the Wall at the sides of the opening and providing a supportfor the bricks of that course which extends across the top of theopening.

6. The combination with a brick wall or the like having an opening, of adoor frame overlapping the borders of such opening and having a rearwardhorizontal flange provided with extensions at both ends, said extensionsoverlying the uppermost bricks at opposite sides of the opening andbeing overlaid by bricks of that course in the wall which bounds theopening at the top, and the flange throughout its length having a widthsufficient to support stably the bricks in said course which overlie theopening.

7. A cleanout door for chimneys comprising a frame adapted to be placedover the borders of a cleanout opening in a chimney wall, havinghorizontal lugs at the rear of its opposite upright sides, projectingoutwardly in position to rest on courses of brick at the sides of theopening and having a thickness approximating the normal width ofseparation between contiguous courses,-

whereby superposed bricks may be laid in a level line on a lug and thelug-supporting course; and the frame having also a horizontal flangeprojecting rearwardly from its upper side of a width sufficient tosupport the bricks of the chimney wall above the opening butinsufiicient to protrude beyond the rear faceof such wall.
